Navigation marks in the Yangtze River are identified by the electronic map of the ship network. There is a ship network in Yibin-Wuhan section of the Yangtze River waterway. In this network, incoming ships become mobile terminals, and send and receive information from all parties through the intermediary of Beidou satellite and communication base station. The condition of the ship itself, including the position, safety and cargo on board, can be sent back to the dispatching management center to guide it to sail more efficiently and environmentally.

The ship network has the function of electronic map. Through Beidou satellite, you can query the trajectory and position of ships in the network and escort them. "If the ship is missing due to the weather, they can also find their position through the ship network." Yu Jiachuan said that with the support of Beidou high-precision positioning technology, the Central Plains electronic lock terminal was developed, and "I" knew where "you" were.

Navigation mark is the "eye" of the ship, and the navigation of the ship must rely on the guidance of navigation lights, especially in the complicated terrain of Chuanjiang. According to the statistics of Chongqing Waterway Bureau of the Yangtze River, during the eleven years from 1990 to 200 1, there were 2 1 17 cases of destroying navigation AIDS in Chongqing-Yichang section of the Yangtze River, resulting in direct economic losses of nearly one million yuan.

This not only increases the burden of waterway maintenance for waterway departments, but also poses a serious threat to the safety of ships. According to the introduction of Chongqing Waterway Department of the Yangtze River, in recent years, the average accidents in Chuanjiang River have been increasing, and the destruction of navigation lights is one of the important reasons.

The navigation marks along the Yangtze River Waterway Bureau-Yangtze River Waterway are more unified, standardized and colorful.
